Description

Technical Field

[0001] The utility model relates to the technical field of electro-erosion processing, in particular to a roller used for electro-erosion processing. Background Art

[0002] Electro-erosion machining is a special machining method that uses the electro-erosion effect generated by pulse discharge between two electrodes immersed in a working fluid to remove conductive materials. During electro-erosion machining, the tool electrode and the workpiece are connected to the two poles of a pulse power supply respectively and immersed in the working fluid, or the working fluid is filled into the discharge gap. The tool electrode is fed to the workpiece through the gap automatic control system. When the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes breaks down the working fluid and generates spark discharge.

[0003] At present, when performing electro-etching processing, it is sometimes necessary to place the workpiece in a special roller for uniform etching. For example, the electroplating roller disclosed in Chinese patent announcement number "CN219174659U" includes a roller body and a support frame, and two groups of support rods are symmetrically arranged on the upper end of the support frame. A cleaning mechanism for cleaning the surface of the roller body is connected to the outer sleeve of the support rod. The cleaning mechanism includes a mounting seat and a cleaning brush plate, and the top of the mounting seat penetrates the two groups of support rods.
